Overview

This is a 3D printer designed by Apsu as a prototype implementation of the Tripteron motion platform, details of which can be found here. This system is both linear and Cartesian in actuation, featuring a fixed build platform, parallel kinematics, and simple construction and operation. The design is still a work-in-progress, and is ongoing primarily in this forum thread.

You can see video of a prototype running here, and a livestream Q&A with the designer here.

The printer was also featured on Hackaday and has garnered a lot of interest as a potential new way forward in printer development.

Benefits

  • Linear actuation provides constant precision throughout the build volume
  • In this orthogonal configuration, the kinematics are simple Cartesian
  • A fixed build platform is simple and allows for consistency and high performance
  • Parallel actuation avoids compounding of mechanical errors, if any exist
  • Framing and assembly are easy
  • Part count is low
  • The mechanism being simple and reconfigurable into different orientations allows for a lot of hackability and room for creative improvements

Challenges

  • Designing and constructing a rigid arm assembly is difficult and demanding engineering, particularly with only common RepRap materials and printed parts
  • Understanding the mechanism is non-intuitive and devising appropriate joints takes some creative thinking
  • The arm assembly weight falls mostly on the Z axis arm, so proper reinforcement and load management takes some engineering work
